 Ross uses 16 curves to a circle!  Gar Graves uses 12 for 072 curves.  Coming off a ross 072 turnout with two sections of GarGraves 072 leaves you about a third of a curve short!  Is there a cheater piece available for this to make up the difference?  In other words the 072 on the Ross turnout is 1/16 of a circle and the GarGraves curve is 1/12 of a circle!  HELP!

Hi John,

 

As the others have indicated, you need to cut a custom piece.  Once you select a track system designed to work with flex track (Ross/Gargraves, Atlas, ScaleTrax) it's time to invest in a Dremel tool and get comfortable with the idea of cutting track.  Even if you plan to only use pre-bent curves, you need to leave behind the mentality that manufactured curves and fitter pieces are your only options.  Cutting that first piece can be a very liberating experience.

John,

As others have stated your going to find certain places where you'll need a custom piece. I use the dremel with a large fiber cutting wheel. With GG track just slide the ties back a little so they're out of your way. Establish your cut line and get out your SAFETY GLASSES (Did I say that loud enough?) You can then cut each rail individually.
go slow so it doesn't grab.

Personally I find it impossible to get a perfect vertical cut so I mark my track with a fine line marker and make my cut about a 1/16th ahead of the mark and use this to sand the rest of the way to the cut line. It'll make a perfect factory edge every time.
It'll also be a useful tool when you start scratch building.

I use the sanding disc on the side for this with a 60 grit disc. Sparks will fly but don't worry it won't hurt a thing but your ends will be perfectly even and perfect vertically.

Might want to update your e mail . I tried to e mail you but I don't need my teeth cleaned

Hi John, I also use Ross and GarGraves.  I also use sectional curves since do NOT like messing with flex.  And I combine different sectional curve diameters to produce an easement effect.  So cutting special lengths/arks of GarGraves is SOP.

 

My suggestion in this case is to cut a 7 1/2-degree ark of O72 thus giving you a 30-degree section to match up with the others.

 

Now as a confirmed "left-brain" and edu as an ME there is a caveat.  GarGraves O72 and Ross O72 (and/or any other diameters) are slightly different.  Now the diameters are so close it really does NOT matter much except to some like me.  So what I also do is use a Ross sectional section mirror imaged diametrically opposed to where a Ross switch is used.  BUT again the difference is most probably actually within their respective manufacturing tolerances.  It just is in my case I build my "tables" as sensationalized sections so they can be more easily moved thus looking for that left-brain precision.

I remember this type of thing when I was building my layout.  Back in 2004-5-6-7 you had the additional option of Curtis track (out of business now for about 5 years).  Curtis HiRail featured 12 pieces to the circle for O54 and above and their switches were identical to the curved section. 

 

If you can find some old Curtis curves and a switch (compatible with Ross and GarGraves), you're in business.  If not, you'll need to cut a custom piece of GarGraves.  I agree with Dave Hikel - it's not that big a deal.  Try it!
